SPECIFICATION forming part of Letters Patent No. 248,900, dated November 1, 1881. Application filed July 19, 1881. (N0 mod 1.)

T 0 all whom it may concern Be it known that we, JOHN G. \VA'r'rs, of Osceola, Clarke county, Iowa, and JULIUS R. WATTS, of Ashland, in the county of Saunders and State of Nebraska, have invented certain new and useful Improvements in Devices for Adjusting the Beat of Pendulnm-Olocks5 and we do hereby declare that the following is a full, clear, and exact description of the inven- IO tion, which will enable others skilled in the art to which it appertaius to make and use the same, reference being bad to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

Our invention relates to devices for adj usting the beat of pendulum-clocks; and it consists of a pendant, carrying the pendulum rod and the verge, and hung upon a stud on the bridge tbrmingthe bearing of one end of the axis of the crown-wheel. The lower part of the pendant forms a sector having teeth to engage n spring-pawl, arranged to hold in place the pendant when adjusted, so that the clock is in heat, as hereinafter fully described.

In the drawings, Figure l is a front elevation of ordinary clock-works with our improved devices attached. Fig. 2 is a vertical section on line :0 .r of Fig. 1, looking toward the right. Fig. 3 is an inner-face view of the pendant de- 0 tached, showing the pendulum -rod and the verge attached. Fig. 4 is a perspective view of the spring-pawl detached. .Fig. 5 is a vertical section through the stud, crown-wheel, and pendant.

A is the pendant, the upper end of which is provided with a hole to adapt it to be hung and swing freely upon the stud a on the bridge 1), forming the bearing of one end of the axis 0 of the crown wheel B, and the upper end of the pendant is held in place on the stud by the spring 61, pivoted at one end to the bridge, and

provided at the other end with a hole to receive the outer end of the axis 0, to allow the spring to hold the pendant in place without any press- 5 me upon the axis. The lower part, A, of the pendant forms a sector, having teeth, as shown atf, to engage the spring-pawl O, which is fastened to a pin, a, on the frame of the clockworks.

A wire, I), is attached at the upper end to the spring, and at the lower end to the clockcase, and this wire is provided with a loop, o for disengaging the spring-pawl from the sec tor A.

The pendulum-rod D is hung to a pin, 0, on

the inner face of the sector-arm.

The verge E is pivoted to one end of thearm F, and the other end of this arm is attached by a movable joint to the pendant, so that the end carrying the verge may be moved upward or downward, as required in ditl'erentsize clocks, to adjust the verge so that its pallets will engage properly with the teeth of the crown wheel. The upper end of the springpawl O is bifurcated, ing projecting points 0 c on each side of the pendant, to prevent it from having any backward or forward movement.

We do not limit ourselves to the particular as shown in Fig. 4, formdevices shown and described for adjusting and holding in place the pendant, as various devices may be employed for that purpose, and it is evident that our improved devices may be varied in size and adjustment to suit different sizes and makes of clocks.

A clock provided with these improved devices being adjusted in the required position, the pendulum is set in motion, and by inserting a finger in the loop I) and bearing the wire downward the spring-pawl is disengaged from the pendant, allowing it to swing freely with the pendulum, and in a few seconds both the pendant and pendulum will stop, when the pawl is allowed to spring upward, engaging again the teeth on the sector-arm, holding the pend- JOHN G.
